ISEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 358,005, dated February 15, 1887.

Application filed August 1, 1885.

invented a new and useful Improvement in Seeding-Machines, whichimprovement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side view, partly in section, of

our improved seeding-machine; Fig. 2, a plan view of the same, and Fig. 3 an enlarged perspective view of the feed-plunger.

This invention relates to an improvement in seeding-machines wherein we provide a series I 5 of drills and a corresponding number of seedplungers penetrating the seed-box and operated by means of a series of pitmen engaging with a shaft, and so disposed that when the machine is moving forward the seed-plunger may have a spiral movement by being swiveled to the pitman and engaging with a lug on the frame-work, so that the seed may be removed from the box and deposited within the drill, all of which will now be fully set forth in detailf In the accompanying drawings, A represents the framework of an ordinary seeder provided with a roller, 13, centrally, and having forwardly the usual seed-box, C, and beneath a series of drills, D. At one end of the roller-axle we provide a pulley, E, carrying a belt, I connecting with a smaller pulley, G, above. This pulley G is disposed upon the end of a transverse shaft, H, journaled to the 3 5 frame-work of the machine and formed with a series of cranks, I, corresponding in number to the number of drills D, of which there are preferably four. Each of these cranks I have forward pitmen J, connecting at their forward ends with a corresponding number of seed-plungers, K, horizontally disposed and penetrating the lower rearward side of the seed-box G. The seed'plunger K is swiveled at its rearward end and connects with the pitman J and the spiral groove L, provided on its periphery to receive thereon a lug, M, secured to the frame-work through which this plunger K operates, so that when a reciprocal motion of the plunger is produced by rotating so the shaft II the plunger K will rotate somewhat in its forward and reverse motion. The

series of cranks I on the crank-shaft H rotate therefrom at different directions, so that the movements of the plungers may alternate or follow each other in a series in entering the seed-box O and removing the seed therefrom. The forward end of the plunger K is provided with a recess, N, of any convenient size, to accommodate the number of grains or quantity of seed to be discharged into the drill, and is placed in such a position that when the plunger is at its forward limit, as shown at 0, Fig. 2, this recess N will be upon the upper face of the plunger, and as it is withdrawn rearwardly from the seed-box the spiral motion communicated by the lug operating in the spiral groove L will cause said plunger K to rotate sufficiently to bring the recess N on the under side of the plunger and deposit the seed into the vertical tube I, and thus deposit it in the rear of the drill D.

The brush 1%, attached to the inside of the seed-box, prevents any seed,except that in the recess N, from being carried out by the plunger in its rearward motion, and the small brush S on the outside of the seed-box is so adjusted as to sweep the bottom of the recess N the moment the plunger begins its forward motion,so as to brush out the seed when gravity is not sufficient to cause the seed to fall out.

In operating the device, the belt F being in connection with the pulleys G and E, when the machine is moved forward the shaft H is rotated, and the pitmen J communicating therewith operate the plungers in a regular series, corresponding with the manner in which the cranks I upon the shaft H radiate there from, and thus the seed is removed from the seed-box and deposited in the drill by the simple rotation of the plungers.

We are aware that a corn-planter has heretofore been provided with a transverse shaft, cranks, and pitmen, and with plungers having seed-recesses; also, that seeders have been pro vided with drill-teeth, seed-tubes, and a roller with operating belt and pulleys.

Vhat we claim as new is In a seeding-machine,the combination of the following elements, in the manner and for the purpose described,viz: the frame-work A,provided with drills D and seed-tube I, and with the roller B, pulleys E and G, and belt F, con- ICO necting therewith, the transverse shaft H, hav- In testimony that we claim the foregoing we ing cranks I, and the pitrnen J, each connecthave hereunto set our hands this 17th day 0f 10 ing at its forward end with a horizontal seed- July, 1885, in the presence of witnesses.
